--- Comment #5 from Jorn Wolfgang Rennecke <amylaar at gcc dot gnu.org> --- (In reply to Patrick Palka from comment #3) > Btw, we already disable the floating-point to_chars on targets without a > binary64 double. So is our test for detecting binary64 not accurate enough, > or are these 16-bit targets whose double type really is binary64? At least in the case of eSi-RISC, it is the latter.
